Wiederabfrage

Wiederabfrage is a German term that translates to "re-querying" or "repeated query" in English. It refers to the act of issuing a query to a system, receiving a response, and then issuing another query based on the information obtained from the first response. This iterative process is common in various fields, particularly in information retrieval, database systems, and artificial intelligence.

In the context of information retrieval, a user might perform a Wiederabfrage when their initial search yields too many or too few results. They might refine their search terms, add or remove keywords, or change the search parameters based on the initial output to narrow down or broaden their search. For instance, if a search for "apple" returns results about both the fruit and the technology company, a user might perform a Wiederabfrage with "apple fruit" or "apple company" to get more specific results.

In database systems, Wiederabfrage can occur when a query requires intermediate results to formulate subsequent queries. This is often seen in complex analytical queries or when querying a knowledge graph where one query's output serves as input for another. This allows for more sophisticated data exploration and analysis by breaking down complex problems into a series of manageable queries.

In artificial intelligence, particularly in areas like natural language processing and question answering systems, Wiederabfrage is a fundamental technique. An AI system might ask clarifying questions to a user if its initial understanding of a request is ambiguous. This helps the AI to refine its interpretation and provide a more accurate or relevant response. This back-and-forth interaction is a form of Wiederabfrage, enabling the AI to gather more context and improve its performance. The efficiency and effectiveness of Wiederabfrage depend heavily on the system's ability to interpret the results of previous queries and formulate intelligent subsequent ones.
